The present study explores time and spatial thermal environment for Daegu, which is a city built on a basin area, according to varying land cover conditions of the earth's surface by analyzing data derived from meteorological observation and satellite images. The study has classified land use by utilizing MODIS satellite images and analyzed land surface temperature. Also, by using data acquired from automatic weather system, the study has evaluated the effects of atmospheric heating caused by city pavements by analyzing the sensible heat flux between the city's land surface and the atmosphere.The results are as follows. 1) Classification of land use in the Daegu area shows 46.64% of urban and built-up area, 1.39% of watersides, 35.19% of forest, 11.43% of crops, and 5.37% grasslands. 2) During the weekdays throughout the year, the land surface temperature was high for Dalseogu, Bukgu, and Seogu regions where industrial complexes could be found. Comparatively, lower temperature could be observed in the woodlands. 3) While the land surface temperature displayed the effects of pushing air upwards during the weekdays in urban areas, the reverse was true for forest regions. During the night, the temperature did not exert any significant influence on air movement.

토양수분은 기후, 토양 및 지표면의 조건 등에 의해 영향을 받는다. 특히, 급격한 도시화 및 산업화의 영향으로 다른 영향인 자들 보다 지표면 조건의 변화가 크게 바뀌고 있다고 할 수 있으며 본 연구에서는 이러한 지표면 조건의 변화가 토양수분에 어떻게 영향을 미칠 수 있는지를 간단한 토양수분 동역학 모형을 이용하여 평가해 보았다. 먼저, 본 논문에서는 토양수분의 시간적 공간적 통계특성을 정량화 해보기 위해 논문의 전반부를 Washita ’92 자료 및 M
